HVAC System Evacuation Flashcard

Front

How does a micron gauge help in determining the effectiveness of an HVAC system evacuation?

Back

It measures the pressure in microns to ensure a deep vacuum.

Front

What is the strategic importance of using a vacuum pump during the evacuation of an HVAC system?

Back

It removes air and moisture from the system.

Front

Explain how manifold pressure measurement is used to verify the evacuation process of an HVAC system.

Back

It verifies that the system has reached the desired vacuum level.

Front

What are the effects of moisture contamination in an HVAC system, and how can it be strategically addressed during evacuation?

Back

Moisture causes corrosion and freezing; it should be removed using a vacuum pump.

Front

Why is it important to remove non-condensable gases during the evacuation of an HVAC system?

Back

They cause increased pressure and reduced efficiency.

Front

Describe the strategic steps involved in the evacuation process of an HVAC system.

Back

Connect the vacuum pump, evacuate the system, and monitor with a micron gauge.

Front

How can a micron gauge be strategically used to ensure complete evacuation of an HVAC system?

Back

By ensuring the pressure drops to a specific micron level.

Front

What role does a vacuum pump play in preventing moisture contamination in an HVAC system?

Back

It removes moisture by creating a vacuum.

Front

How does manifold pressure measurement help in identifying non-condensable gases in an HVAC system?

Back

It detects pressure anomalies indicating non-condensables.

Front

What strategic actions should be taken if moisture is detected during the evacuation of an HVAC system?

Back

Continue evacuation until the micron gauge shows a stable low reading.
